摘要
本文阐述了一种使用3.7~11.1TBq60Co工业探伤源的特殊集装箱检测系统。借助于采用高灵敏度阵列探测器以及其他技术措施,此种60Co集装箱检测系统具有良好的检测性能。它对100mm铁屏的“反差灵敏度(CI)”及“像质值(IQI)”分别等于0.7%和2.5%,而其“铁穿透本领(SP)”则达到约240mm。60Co集装箱检测系统比加速器型检测系统便宜、可靠、占地少,而其“穿透本领”则显著高于X射线机型检测系统。
This paper presents a special kind of container inspection system, in which a 60 Co industrial radiography source of 3.7~11.1 TBq is used as the radiation source. By the adoption of high sensitivity array detector and other technical solutions, this 60 Co container inspection system possesses nice properties. Its “image quality indicator(IQI)” and “contrast indicator (CI)” for 100 mm steel plate are equal to 0.7% and 2.5% respectively. Its “ steel penetration (SP)” is about 240 mm. The 60 Co container inspection is much cheaper and more reliable than accelerator inspection system, and the dimensions for its installation and operaction is much smaller. The “SP”of 60 Co system is much higher than that of X ray machine inspection system. (
